Undefined Data
Undefined Data
If the CDR register is not read before further incoming data is converted, the corresponding
Overrun Error bit in the SR register (SR.OVREn) is set.
In the same way, new data converted when DRDY is high sets the General Overrun Error bit in
the SR register (SR.GOVRE).
The OVREn and GOVRE bits are automatically cleared when the SR register is read.
Warning: If the corresponding channel is disabled during a conversion or if it is disabled and
then reenabled during a conversion, its associated data and its corresponding EOC and OVRE
flags in SR are unpredictable.
